Abstract：Objective　Analyze and approach sudden death and the reasons for the success and failure in on-the-spot resuscitation,in order to improve success rate in on-the-spot resuscitation.Methods　Colle cted consecutive 874 records of sudden death patients who received prehospitale mergency medical care provided by Shanghai medical Emergency Center during Jan.1999 through Dec.1999 and retrospec tive study was performed by referencing Utstein mode statistics.Results　70.44% of the patients had history of cardiovascular diseases before sudden death.High sudden death incidence happened in the age group of 60 to 84 years that accounted for 64.48% of all the patients;happened more often on males than on females;and happened basically at home,that accounted for 93.80%of all the patients.Among the 24 patients who received CPR by on-lookers,16(66.67%)were responded to the resuscitation.However,the 815 patients who received CPR by EMT,only 43(5.28%) of them were effective.The two results have significant differences (P＜0.01) .The mean time interval from call to arrival at site,was 8.16 min and 9.90 min respectively in those who received resuscitation effectively and ineffectively. By using defibrillation and intubation,the effective rate of resuscitation was 12.59% and 28.22% respectively.In patients who didn’t received defibrillation and intubation,the effective rate were only 5.89% and 1.92%.It reveals signifi cant differences (P＜0.01).There were 58 cases(6.91%)who responded to on-the-spot resuscitation and succeeded only on 1 case(0.12%).The incidence rate of prehospital sudden death patient was highest in winter and the peak happened at 7 am in a day.Conclusions　The emergent interference death including:①identify,prevent and treat the high risk factors of sudden death; ②popularize the knowledge of appl ying primary emergency care with CPR as the basic procedure;③make effort to shorten the emergency response time,I.e.time interval from call to arrival at site ;④regulate resources according to the season and time.
